I am converting over from the factory dual cats and going with a 3" Random Tech single cat (along with Hooker 2055's). The Random cat has 2 a.i.r. fittings on it, do I hook up the factory dual fittings to it or just use 1 and plug the other one with the supplied plug? It is the direct replacement from Random #13-903002 for a single cat car. Thanks for the help.

I have a random tech cat for my single exhaust...I just plugged the side that my air did not go too.
